Excitation caging in a vertex-frustrated quasiperiodic Einstein artificial spin ice
T. Wang, F. Museur, G. M. Macauley +5
Naturally occurring bulk quasicrystals are rare, and magnetic instances are rarer still, with chemical constraints typically permitting the synthesis of approximants rather than tr…
Realizing Blume-Capel Degrees of Freedom with Toroidal Moments in a Ruby Artificial Spin Ice
Luca Berchialla, Gavin M. Macauley, Flavien Museur +4
Realizing exotic Hamiltonians beyond the Ising model is a key pursuit in experimental statistical physics. One such example is the Blume-Capel model, a three-state spin model, whos…
Magnetic ordering in out-of-plane artificial spin systems based on the Archimedean lattices
Aleksandra Pac, Gavin M. Macauley, Jamie R. Massey +4
Artificial spin systems, sometimes referred to as artificial spin ices, are arrays of coupled nanoscale magnets that order according to the lattice geometry, nanomagnet shape and m…
Five-stage ordering to a topological-defect-mediated ground state in a buckyball artificial spin ice
Gavin M. Macauley, Luca Berchialla, Peter M. Derlet +1
Artificial spin ices are arrays of coupled nanomagnets, which exhibit a variety of fascinating collective behaviour including emergent magnetic monopoles, charge screening, and nov…
Impact of planar defects on the reversal time of single magnetic domain nanoparticles
Hugo Bocquet, Armin Kleibert, Peter M. Derlet
Recent experimental investigations of individual magnetic nanoparticles reveal a diverse range of magnetic relaxation times which cannot be explained by considering their size, sha…
A robust theory of thermal activation in magnetic systems with Gilbert damping
Hugo Bocquet, Peter M. Derlet
Magnetic systems can exhibit thermally activated transitions whose timescales are often described by an Arrhenius law. However, robust predictions of such timescales are only avail…
